Abstract (en)
[origin: WO2017076758A1] An ultrasound system (100) for providing an ultrasound image of a volumetric region comprising a region of interest (12) comprising: a probe (10) having an array of CMUT transducers (14); a beamformer (64) coupled to the array and adapted to control the ultrasound beam steering and provide an ultrasound image data of the volumetric region; a transducer frequency controller (62) coupled to the beamformer and adapted to vary operation frequencies of the CMUT transducers within the frequency range, which frequency controller is arranged to set the operation frequency to a first frequency for the ultrasound beam steered in the volumetric region and to set the operation frequency to a second frequency for the ultrasound beams steered within the region of interest, the second frequency being higher than the first frequency; wherein the system further comprises an interferer analyzer (69) coupled to the transducer frequency controller (62), said interferer analyzer is adapted to vary at least one of beam steering parameters when the second frequency is above a threshold frequency value so as to mitigate a quality reduction of the ultrasound image due to the use of frequencies above the threshold.
